Application tiled January 18. 1892. Serial No. 418,368. (No model.)

To all whom it may concern:

Be it known that I, ALBERT B. DISS, acitil zen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented an Improvement in Wheels or Rollers for Casters and otherArticles, of which the following is a specification.

In manufacturing caster-wheels it has been usual to make use of acast-brass wheel or roller, especiallyin the better class of casters;but in practice it is found that the cast metal 1s comparatively soft,and under the strain or Weight to which the caster is usually subjectedthe bearing for the pivot-pin gives Way either by wear or by bending,and sometimes the hub portion of the caster-wheel breaks away, and inaddition to this it is usual to turn olf the surface of the caster-wheelwith deep circular recesses at each side to lessen the weight of metalnecessary; but these recesses frequently become filled with dust andlint and it is difficult to clean the same because of the angularbottoms of the recesses. In some instances the caster-wheel has beenmade of eplrate pieces, one of which is a perforated The presentinvention relates to the manner hereinafter described in which thecaster or other wheel is constructed, whereby great strength isobtained, the risk of injury is lessened, and the expense of the wheelis greatly decreased.

In the drawings, Figure l shows a section of a tube employed by me. Fig.2 is a section of one of the disks. Fig. 3 is a section of the wheelwith four disks after the parts have been put together, and Fig.4is asimilar View of the caster-wheel with three disks.

I make use of a metal pipe or tube of a diameter corresponding to thediameter of the caster-wheel, or nearly so, and this pipe or tube ispreferably of brass or other ornamental metal and is sufficiently thickfor obtaining the necessary strength. The tube is cut olf into sectionsA, the length of each section corresponding to the width or thickness ofthe caster-wheel.

I make use of metal disks BB, cut out from suitable sheet metal-such assheet-steeland having central holes of a size adapted to receive the pinor pivot of the caster-wheel, and each disk is stamped up conically, and

in making a caster-wheel two, three, four, or more of these disks B areset together with the convex sides outwardly, and these are thenintroduced into the tube-section A and held by suitable tools while thetube-section A is closed around theedges of the disks B, so that suchtube-sectionAreceives a convex exterior surface, as shown in Figs. 3 and4., and the edges of the disks become embedded into the tube-section A.Hence it is impossible for the disks B to escape from the tubesectionforming the periphery of the casterwheel or to become loosetherein,because the tube-section and its ends are contracted in diameterand become smaller at the ends than the disks. The caster-wheel thusmade might be employed in the ordinary frame or jaws of. the caster orused in any other manner or in any other device, the axis or pin passingthrough the central holes 2 of the disks B, and the conical shape whichhas been given to the disks B causes the bearings of such disks uponthe-pivot-pin to be in line or slightlybeyond the edges of thetube'section A.

When only two disks-such as shown in Fig. Z-are employed, the anglesbetween the surfaces of the disk and the interior of the tube-sectionmight be lled with solder or soft metal. Usually it is advantageous toemploy three disks, as shown in Fig. 4, the central disk being thickestand slightly largest, or four disks may be used, as in Fig. 3,the twoinnerdisks being slightly thelargest. The disks are preferably cleanedand polished before placing them in the tube-section. This may be doneby a rumbler or other appliance. After the parts are put together thewheels may be dipped in a proper plating solutionsuch as brass or bronzesolution-to coat the outer surfaces of the wheels, so as to be ofuniform color, and they may then be buffed or polished. Wheels made asaforesaid are much stronger than the wheels heretofore oonstructed, andwith brass or other ornamental metal they are much cheaper than thoseheretofore made.

I claim as my invention- 1. The caster-wheel having arim composed of atube-section and two or more centrallyperforated convex disks placedwithin the tube-section with their convex faces outwardly and heldwithin the tubular rim by the said IOO rim being compressed and closedinwardly, held Within the tubular rim b'y the said rim substantially asset forth. being compressed and closed inwardly, subro 2.
